[aprssig] New Version .49 of UZ7HO Soundmodem Released

A new version .49b of the excellent "UZ7HO Soundmodem" soundcard soft TNC has
been released as of 29 Aug 2013.
As usual, it can be downloaded from my website at:
<http://wa8lmf.net/miscinfo>
Scroll about 3/4ths of the way down the list of downloadable stuff and look for
"UZ7HO-Soundmodem-Install-Ver-0.49-Beta.exe". Note that unlike the version
on Andrei's own website at:
<http://uz7ho.org.ua/packetradio.htm>
that is a single .EXE file contained in a zipfile, the package on my site is a
full-blown Windows "wizard"-type installer that automatically creates a program
folder, entries in the Windows Start Menu, and includes several readme files
and a User Manual in .PDF form.
Some of the change log entries for the last several versions:
SCM v0.49b changes:
- Improved RX-part of the modem (improved ATC and added interpolation)
- Improved DCD for 1200 and 2400 bauds
- Fixed some bugs in the AX.25 L2-layer protocol
- Expanded features for non-standard AX.25 frames for SAT-operations.
- Version number now displayed in title bar
SCM v0.45b changes:
- Added "6dB Pre-Emphasis filter" option.
Pre-Emphasis filter it's a high-pass filter that emphasizes the high
frequencies in the audio spectrum. Preemphasis increases the level of
high frequencies by 6dB per octave. It might help to receive signals
at 1200 and 2400 bauds if the frequency response of the receiver is not
a "flat".

- Added "NRMonitorLines" option for limit number of lines "Monitor" window
(10-65535).
- Improved compatibility with the AGWPE and MixW AX.25 Protocol (reduction of
REJ collisions)
and fixed some small bugs.

traffic.
